Abstract
This study aims to develop a simple yet accurate adaptive homogenization approach for modeling the effective elastic properties of concrete for the whole hydration range from early age to hardened state. Considering available data from a similar microstructure, the method accurately accounts for the impact of cement hydration degree on the effective elastic properties of the heterogeneous concrete mixture. The simulation results have been validated against experimental data and demonstrate exceptional agreement. Also, we have detailly discussed the role of water and the effect of the destructive and non-destructive measurement methods. The model’s simplicity and accuracy make it highly applicable in practical engineering scenarios.
期刊介绍：
JACT is fast. Only 5 to 7 months from submission to publishing thanks to electronic file exchange between you, the reviewers and the editors.
JACT is high quality. Peer-reviewed by internationally renowned experts who return review comments to ensure the highest possible quality.
JACT is transparent. The status of your manuscript from submission to publishing can be viewed on our website, greatly reducing the frustration of being kept in the dark, possibly for over a year in the case of some journals.
JACT is cost-effective. Submission and subscription are free of charge . Full-text PDF files are available for the authors to open at their web sites.
